Brunnian local moves of knots and Vassiliev invariants
Akira Yasuhara
K. Habiro gave a neccesary and sufficient condition for knots to have the same Vassiliev invariants in terms of -move. In this paper we give another geometric condition in ter…
Impact of CP phases on the search for top and bottom squarks
A. Bartl, S. Hesselbach, K. Hidaka +2
We study the decays of top squarks (~t_{1,2}) and bottom squarks (~b_{1,2}) in the Minimal Supersymmetric Standard Model (MSSM) with complex parameters A_t, A_b, mu and M_1. We sho…
Signature of rotors
Mieczyslaw K. Dabkowski, Makiko Ishiwata, Jozef H. Przytycki +1
Rotors were introduced in Graph Theory by W.Tutte. The concept was adapted to Knot Theory as a generalization of mutation by Anstee, Przytycki and Rolfsen in 1987. In this paper we…
A factorization of the Conway polynomial and covering linkage invariants
Tatsuya Tsukamoto, Akira Yasuhara
J.P. Levine showed that the Conway polynomial of a link is a product of two factors: one is the Conway polynomial of a knot which is obtained from the link by banding together the…
Graded persisting activity of heterogeneous neuron ensembles subject to white noises
Hideo Hasegawa
Effects of distractions such as noises and parameter heterogeneity have been studied on the firing activity of ensemble neurons, each of which is described by the extended Morris-L…
